the nerve, into 15 or 20 pair of oval, entire 

 lobes. The frudifications make their firfl ap- 

 pearance in two rows of fmall, round, pale^ 

 diftin<5l dots, near the edges of thele Jobes„ 

 Thefe dots, as they grow riper, run together in 

 marginal lines, the edges of the lobes being a 

 little reflex'd or contradted -, and in the old plants 

 the under fides of the lobes arc totally covered 

 with brown capfules, as in the genus of ACROS- 

 TICHUM. The fruftifications are contained 

 within a fingular laciniated, or radiated invoh* 

 crum. The capfules are pale brown, and fur- 

 rounded with a dark red articulated fnining ring. 

 The younger leaves are barren, and fofter than the 

 fruitful ones; their pinnules wider, and of a 

 paler green •, fometimes llightly and irregularly 

 crenated.
